About Textpresso Categories/Ontology Copyright Downloads Feedback Home Query Language Search User Guide
Enter keyword(s) and/or category/ies. Selecting categories for a query makes a search more specific. For example, you can retrieve sentences that contain the word HSN and a Oryza sativa gene name by typing the keyword 'SPW1' and choosing the category 'gene (Oryza sativa)'. A category hit occurs when a particular word or phrase in the sentence is defined as a member of a particular category. Categories will be concatenated by a Boolean 'and' operation to other categories and keyword(s) if present. To search for terms in categories, click on the Categories/Ontology link above.
Keywords
Separate multiple, required keywords by white spaces (Boolean 'and').
Separate multiple, alternative keywords by a comma with no white spaces (Boolean 'or').
Enter phrases in double quotes, and put a '-' sign in front of words which are to be excluded.

Narrow your search results with filter:
Put a '+' sign in front of words which have to be included, a '-' sign in front of words which have to be excluded. Enter the field of the word, viz author, title, year, journal, abstract, type or sentence in square brackets. Enter phrases in double quotes.
For example, to find all the papers in the search result that have Jack as author, but not John, enter +Jack-John[author]. To exclude all papers that have the phrase double mutant in title, enter -"double mutant"[title]. You can combine several filters and enter something like +Jack-John[author] -"double mutant"[title] +1994[year] -review[type].

Title: Rice embryo globulins : amino-terminal amino acid sequences , cDNA cloning and expression .
Author: Sun JL Nakagawa H Karita S Ohmiya K Hattori T
Journal: Plant Cell Physiol . Citation: V : 37 ( 5 ) P : 612-20 Year: 1996 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub8819309 Accession (PMID): 8819309
Abstract: A globulin fraction prepared from rice embryos contained polypeptides or polypeptide groups of 49 kDa ( designated REG1 ) , 46 kDa ( designated REG2 ) , about 35 kDa , 32 kDa and 25 kDa . The amino-terminal sequences of REG1 and the major polypeptide in the 35-kDa group were identical , suggesting that the REG1 polypeptide undergoes partial proteolytic processing that removes a carboxy-terminal region . A cDNA clone , designated pcREG2 , encoding REG2 was isolated , and its nucleotide sequence was determined . The deduced amino acid sequence of REG2 was found to be 68% identical to that of the maize GLB2 globulin . Reg2 mRNA was present at high levels during embryo development for up to 14 days after flowering ( DAF ) . Lower levels were found 20 DAF when the maturation of embryos was almost completed , and at the dry mature stage . Reg2 mRNA almost disappeared upon imbibition of isolated dry mature embryos but it was re-induced at a low level by further treatment with ABA . The expression of Reg2 was not induced by ABA in suspension-cultured cells , unlike that of Osem , one of the late embryogenesis abundant protein ( LEA ) genes .

Title: Proteomic analysis of rice embryo : an approach for investigating Galpha protein-regulated proteins .
Author: Komatsu S Abbasi F Kobori E Fujisawa Y Kato H Iwasaki Y
Journal: Proteomics Citation: V : 5 ( 15 ) P : 3932-41 Year: 2005 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub16152656 Accession (PMID): 16152656
Abstract: The rice dwarf1 ( d1 ) mutant , which lacks the alpha subunit of a heterotrimeric G protein ( Galpha protein ) , shows abnormal morphology due to shortened internodes , dark green leaves and grains that are small and round . Proteome analysis was used in this study to aid in determining the function of Galpha protein in rice embryos . Using 2-DE , seven seed embryo proteins were shown to be down-regulated in the d1 mutant as compared with its wild type . These seven proteins included a receptor for activated C-kinase ( RACK ) and six rice embryo globulin-2 proteins ( REG2 ) . The six REG2 have similar molecular masses with minor differences in pI . In addition to the reduced accumulation of RACK in the d1 mutant , the increase in QL/d1 , in which a constitutively active form of the Galpha protein is expressed , was significantly higher as compared with wild type . The level of accumulation of these seven proteins during seed development and maturation did not change significantly until the 2nd wk after pollination . Reduced accumulation of these seven proteins started in the d1 mutant at the 3rd wk after pollination , and continued until seed maturation was complete . All seven proteins were completely absent 24 h after imbibition in both d1 mutant and its wild type . However , the phytohormone abscisic acid promoted the expression level of RACK after imbibition in the wild type as compared with d1 mutant . These results suggest that RACK is regulated by Galpha-protein and plays an important role in a basic cellular process as well as in rice embryogenesis and germination .
